Hi Emmalyn,
I'm so sorry you are having such a low time right now! And as others have said, we get it. Many of us have been there. We are here for you to vent to, cry to, lean on...
I'm a few years older than you. I've been married and divorced. I remarried a wonderful, wonderful man...and he died 6 years later. I found myself on my own again. Starting over--again.
I've been helped by counseling on a few occasions in my life--my grief being one of them. Can't recommend finding a good counselor enough.
And you know what? I am not too old to find someone with whom I can spend the rest of my life--I'm not too old to live the life I imagine. So, if I'm not too old, you are not to old. There is plenty of time to live a good life--the kind of life you imagine!
